- CRUDE-OIL BURNER.

Application flledfDecemb'er '14, 1926. Serial no. 154,749.

This invention relates to new and useful improvements in crude oil burners, and has "for its primary object to provide a burner of the general ty e wherein an oil pipe is v arranged longitu-inally through an air or steam feed pipe so that said steam or air will become properly mixed with the oil to provide the proper combustion at the fuel ejecting end of the burner.

The primary object of the invention resides in the provision of a burner of this character wherein the discharge end of the oil pipe may be arranged in predetermined adjusted'position outwardly of the end of the air or steam pipe so as-to prevent carbonization at the tip of the burner'and the equal combustionof fuel oil as well as the conservation of the oil with a greater degree of heat and efficiency.-

A further and important object is to provide a burner of this character wherein no vaporization of the oil will occur within the burner, but entirely within the furnace fire box.

A still further object is to provide a burner of this character wherein the oil pipe may be easil adjusted Within the steam or air jacket so t at the ejection end of the oil pipe may be properly adjusted with respect to the ejection end of the steam or air jacket.

Other objects will become apparent as the 7 nature of the invention is better understood, the same comprising the novel form, combination, and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate through both of the figures: v

Figure 1 is a top plan view of a crude oil burner constructed in accordance with the present invention, and

Figure 2 is a detail longitudinal section thereof.

Now having particular reference to the drawing wherein there is disclosed a crude oil burner constructed in accordance with the present invention, 5 designates an elongated oil pipe, one end of which is flattened and outwardly flared as at 6 for providing an oil emitting nozzle, while the other end thereof is externally threaded as at 7 so as to permit of the attachment to the oil pipe a source of oil supply. Surrounding corresponding parts the oil ipe 5 is a pipe-like jacket 8, the forward end of which is somewhat flattened and-outwardly flared as at 9. The main tion of this jacket 8 as well as the flattened and flared end 9 is of such dimensions that the main portion and body thereof will be in spaced relation with "the main-body and nozzle end of the oil pipe 5.

The pipe-like jacket 8 is of less length than the length of the oil pipe and terminates at its inner end in considerably spaced relation with the threaded end 7 of the oil pipe, said end of the jacket being threaded as at 10 for threaded engagement within an eduction opening 11 of a hollow globe-like which opening is to be injected air or steam under pressure. 7

Threaded within openings at the top and bottom sides of the flattened and flared end of the pipe-like jacket 8 are set screws 15 for forced engagement with the nozzle end 6 of the oil pipe 5 so as to maintain the burner end of the oil pipe in spaced predetermined relation with the air or steam jacket 8.. Obviously, by loosenin the set screws 15, the oil pipe 5' may be a justedfllongitudinally within the jacket 8 and head 12 so that the combustion end of the oil pipe maybe projected to the desired degree beyond the exhaust end of the jacket 8 'so as to secure the proper combustion of the fuel;

The jacket 8 may be and preferably is formed at its opposite side with attaching lugs 16 within which are openings 17 to permit the burner to be properly anchored within a furnace fire box.

It will thus be seen that I have provided a highly novel, simple, and eflicient crude oil burner that is well adapted for all the purposes heretofore designated, and even though I have herein shown and described the invention as consisting of certain detail structural elements it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the ap ended claim.

Having thus escribed the invention, what I claim as new and desire to secure by Let ters Patent is y In an oil burner of the class described, an air or steam jacket having a flared and flattened discharge end, a head threaded at its inner end on the opposite end of the jacket, the outer end of said head being 0 ened, the top of the head being provided with an air or steam inlet, whereby air or steam may be introduced in the jacket, an elongated oil pipe extending longitudinally through the Jacket and through the outer open end of the head, a packing gland surrounding the pipe and threadedinto theouter open end of the head, the forward end of the oil pipe being flattened and flared to provide an oil ,dis- 1 -ycharge nozzle, the discharge end of which projects beyond the outer end of the discharge end of the steam or air jacket, said oil pipe adapted for slidable movement through the jacket for adjusting the distance between the outer ends of the nozzle and the jacket respectively, the rear end of the oil pipe being threaded for communication with an oil supply pipe, and set screws threaded through the to and bottom of the flattened end of the jac et for engagement with the flattened top and bottom faces respectively of the discharge nozzle of said oil pipe for holding the same in any predetermined adjusted position.

In testimony whereof'I affixiny signature.
